Acute Transverse Myelopathy

      Acute transverse myelopathy (myelitis) is an acute inflammation of one or more segments of the spinal cord. It can be associated with multiple sclerosis, infections, vaccinations, systemic malignancy, vascular disease, and autoimmune disorders. Acute lesions are hyperintense on T2-weighted images and hypointense on T1-weighted images and may demonstrate cord enlargement. Enhancement with gadolinium has been reported. Chronic lesions often show persistent increased T2 signal from residual gliosis. Severe cases may lead to cord atrophy. Endnote
